Verdict
The clearest difference is in-app purchases: MANtenatal at none against Flex's 3. MANtenatal also leads on ads (none vs shown) and iOS requirement (13.0 vs 16.4). Flex's advantage is update cadence (every 10 days vs every 8 months). On price, review sentiment and device support there is nothing between them.
